Ease of Use
The primary reason why this product is the go-to choice for small hole repairs in asphalt pavements is the ease of installation. There is no long, extended process of preparing or mixing materials. Instead, the air does most of the work. You simply pour the mix directly into the hole, compact it with simple manual tools (metal tamper or piece of lumber), and leave it to air dry. The mix turns into a permanent surface patch after extended contact with air.
The drying process, also known as curing, is very important to establishing a solid, stable surface that lasts a long time. If you want a permanent repair for your asphalt, you need to make sure the entire process is done correctly. If you want to speed up the curing stage of your pavement repair project, you can try a few recommended tips.
You can use gravel to create a more dense space within the hole, which may help to establish lasting strength. Just fill the hole with gravel, little by little, while using your compacting tools to compress the gravel with each layer. Do not fill the hole all the way to the top; be sure to leave 2 inches of space below the surface line for your cold patch mix.
Pouring Your Mix
As you pour your mix, exceed the surface line by half an inch. This means that your mix should go over the top of the hole by a ½ inch. Then use your compacting tools to compress your material down until it is properly flattened. You may need to repeat this step two or three times to get a proper fill.
Asphalt cold patch mix cures by having contact with air. You can speed up the drying process by using hair dryers or commercial paint dryers. If you are going to use a hair dryer, you will need to manually operate it in a steady, sweeping motion to ensure even curing. The material is near dry when you cannot easily press into the surface with your hand.

For large-scale pavement repair jobs, you need a professional paving company. They have the training, equipment, and resources to provide dependable work in a convenient time frame. Be sure to choose a company that is licensed, bonded, and insured, and retains decades of experience in the road construction industry.
Asphalt Driveway Pavers Cost in South Africa ?
Asphalt driveways can last as long as any hard surface if installed and maintained properly. However, usually the weakest point of the driveway is the edge. Edges are prone to several defects. The most common defect is cracking. Cracks generally form parallel with the edge of the driveway. This phenomenon happens usually when expansive soil is present under the driveway. The soil expands and contracts causing cracks that eventually transmit through the asphalt surface. Installing a decorative edge made from cobblestone or brick pavers will interrupt the point of expansion where the asphalt meets the yard. The edge will keep the asphalt from shifting; thus eliminating the cracking in the pavement.
Another source of problems is invasive vegetation. Zoysia grass and chickweed will easily migrate or expand through asphalt, especially fresh asphalt that is less than 3 years old. Grass can grow into an asphalt driveway by as much as 3 feet if not properly attended to. Controlling invasive grasses typically involves a regiment of spraying the edge with a herbicide to prevent growth of grass. Doing this works well, but isn't 100% effective. Zoysia and Chickweed spread by sending out runners under the soil. A home owner trying to protect their driveway might be satisfied with the progress they have made with herbicide treatments because they have kept an edge free of vegetation.
But eventually you may still see some sprouts pop up through the asphalt because a runner was able to escape the effects of the herbicide by traveling underground. Decorative edging installed on asphalt driveways by a qualified paving contractor will eliminate the potential of migrating grass invading the asphalt. When cobblestone or paver bricks are installed properly, it will create a solid barrier between the yard and edge of the driveway. Substrates used to hold the edge is non porous, therefore it leaves no voided areas for vegetation to grow. If invasive grass is left unattended on an exposed asphalt edge it will eventually ravel the edge. Cobblestone or brick paver edging will prevent damage from grass.
Decorative cobblestone and paver edges also keep vehicles from driving off the edge of the driveway. Driving off and on an edge of an asphalt driveway will eventually cause the edge to ravel, or break off. Not only is this an expensive repair, but it also leaves the home owner's yard not looking its best. Repetition will rut the yard and cause a bare spot, which eventually turn to mud. Decorative edges installed properly will reinforce the edge of the pavement, and also create a curb. The curbing effect will keep vehicles on the driveway and out of the yard.
Another important feature of decorative edging is its ability to control drainage. Not all, but some home owners desire a protective barrier against erosion or unwanted rain water. This is generally achieved by installing a machine curb or roll curb on the edge of the driveway. Machine curbs and roll curbs are formed from asphalt material. A decorative edge constructed of cobblestone or paver bricks can achieve the same results and look better doing it. A homeowner that has unwanted drainage or silt erosion from a neighboring property can be stopped by installing a decorative edge or curb.
Decorative edges add aesthetics and beauty to the home. A properly installed edge by a qualified paving contractor looks great and guards your investment by eliminating defects. Decorative edges can add up to 10 years to the life span of your new asphalt driveway. If you plan on replacing an asphalt driveway, you should consider implementing a decorative edge or curb into the design.
